22 point Tory lead from YouGov
The monthly YouGov poll for the Sunday Times has topline voting intention figures, with changes from YouGov's last poll, of CON 47%(+1), LAB 25%(-3), LDEM 18%(+3). The poll was conducted on the 10th and 11th July.
It looks like a drop for Labour, but the comparisons above are from YouGov's last Telegraph poll, which itself showed an increase for Labour and drop for the Lib Dems. These figures are identical to the YouGov poll before that, suggesting that the bigger picture for voting intention polls is one of no change.
UPDATE: The Sunday Times got the figures wrong! The actual voting intentions were CON 47%(+1), LAB 25%(-3), LDEM 16%(+1).
